I have just installed FreeCAD and started to play around with it, trying to generate two adjacent cubes and mesh them. Knowing how to do this with Salomé, I would need to make a partition first in order to get a matching mesh at the interface. How do I do this in FreeCAD? Should I better ask that kind of questions at the FreeCAD forum?Second question: What do I have to install in order to see the Elmer module (or what already exists of it)? I have installed the stable Win64 version.

Concerning your question regarding .unv export, you simply mark the part you want to export and choose File->Export-> Choose .unv .The exported files can than be easily translated with ElmerGrid.You can already define some boundary groups by simply applying constraints (e.g. fixed boundary) and exporting the mesh. It does not matter which type of constraint you use in Freecad, it is just for grouping the boundaries.

Hi,How did the Elmer module work with FreeCAD. Were the tests successful?I am interested in how this works. I need to simulate shock and vibration on a PCB assembly and could output an STP file that may be loaded into FreeCAD. But as I am new to Elmer and the whole Vibration Analysis, I would be interested in how you efforts were going.

There is no Elmer Integration done yet. Before starting the integration the multibody-meshing has to be polished a little bit further. Therefore, testers are welcome to give feedback. You also can use FC to simply create your complete mesh including boundary and domain definition for ElmerGUI 'without' the need of Gmsh and Salome. BR,Wil

No there is no specific tutorial for creating a multi-body mesh. Please see the tutorials for the FEM-Workbench in the wiki (http://freecadweb.org/wiki/index.php?ti ... tilever_3D, http://freecadweb.org/wiki/index.php?title=FEM_Module) to learn how it is intended to work with FEM-WB. EDIT: This is needed to see/find the used Constraint-elements/definitions from the current in FC used solver 'calculix'. These definitions are used for setting boundary-constraints (they are also exported with their FC-name to .unv.) while material definitions are used to create different domain/body. The mesh can be tuned by using mesh-regions (which are not in master now but you can use the femmeshregion branch of bernd to test it, see below).
